PHILIP EICKENBERfi, OF MINNEAPOLIS, MINNESOTA.

BOX-HINGE.

Application filed January 11. 191."

To all whom it may concern:

Be it known that I, PHILIP EICKENBERG, a citizen of the United States, residing at Minneapolis, in the county of Hennepin and State of Minnesota, have invented certain new and useful Improvements in Box- Hinges, of which the following is a specification.

My invention relates to metallic boxes for installing electrical apparatus and has for its object particularly to provide a hinge for the cover of the box formed of the material of the box and oi the cover and having the parts so constructed and related that when the coveris closed the hinge portion will be sealed from the outside atmosphere. The construction, also, is one which makes practicable ready and ellicient assembling of the cover and box portion.

The full objects and advantages of my invention will appear in connection-with the detailed description thereof and are particularly pointed out in the claims.

In the drawings, illustrating the application of my invention in one form, Figure 1 is a rear View of a box showing my hinge construction. Fig. 2 is a top plan view of the same. Fig. 3. is a transverse section view taken throughthe hinge. Fig. 4'is a sectional detail showing the manner of assembling the box and cover to form the hinged connection between the two. Figs. 5 and 6 are sectional details similar to F i 4 showing the position of the parts of the hinge when the cover is closed and open,

respectively. Figs. 7 and 8 are enlarged in-'.

side views of portions of the cover and wall of the box showing the manner of forming the parts for the hinge. 5

As illustrated, the rear wall 10 of the box has a portion cut out at the top edge, as indicated at 11 in Figs. 4, 5, 6 and 8, said cut-out portion being formed into a tongue 12 having an outwardly-turned extremity or lip l3 and a curved bearing portion 14. The cover 15 of the box has tongues 16 cut out of the rear flange of said cover and bent outwardly at the edge 17 so to leave a short section 18 of the cover flange, as best shown in Figs. 4 to 7 inclusive.

The manner of assembling the cover upon the box is well shown in Fig. 4. As there illustrated. the section 18 of the cover flange. which becomes the pintle of the hinge, is forced inside of the outwardlycurved lip 13 of the tongue 12. When the Specification of Letters Patent.

cover is forced down from the pee shown in Fig. i, the tongue 12 snaps F the position shown in Fig. 5, where outwardly-turncd lip 13 engages the so"? tongue 16 and the edge of the cover to 16 engages the curved bearing-portion 14 of the tongue 12. Also, the pintle piece engages within the curt ed hearing portirm l4. lVhen in this position the not only'hingedly connected with. t "Well it) of the box, but the rela i ment of the parts effectively 5 up hinging port-ion, rendering the a. (in proof. The cover swing-x og: n upon the hinge formed by the pin 1 within the curved bearing-portic s 1% and is lim. ited in its opening mo .rt by engage-- ment of the cover ton .o with the box wall 10 at the point tongue 12 is pressed out from said hex we.

It will be apparent that from the prac tice of my invention an exceedingly efiicient box hinge may be formed directly out of tle material of the box and "cover, said hing being capable of the utmost ease of assembling and having the very great advantage of sealing the openings which otherwise would be created by the formation of the hinge from the material of the box and cover Walls.

I claim:

1. In combination with the overlapping rear and cover walls of a box, a hinge formed of the material of said walls and comprising a tongue out on three sides from the cover wall so as to leave a portion of the material at the edge of the cover wall to form a hinge pintle, and a tonguecut from said rear wall and formed with afcurved bearing-portion to receive and encirele said pintlc, said pintle being rotatably secured to the box between said encircling tongue and the rear wall of the box.

2. In combination with the overlapping rear and cover walls of a box, a hinge formed of the material of said walls and comprising atongue out on three sides from the cover wall so to leave a portion of the material at the edge of the cover wall to form a,hinge pintle, and a tongue out from said rear Wall and formed with a curved bearing-portion to receive said pint-le, said cover tongue being turned outwardly at an acute angle and the end of said box wall tongue being curved outwardly so that the pintle portion may be pushed under cover is? if; f?
